  1. Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

    Java was developed to achieve five main goals. These are: 1. Java should be easy to learn, object-oriented, and distributed. 2. Java should be safe and strong. 3. Java should not depend on any computer architecture or platform. 4. Java should function well. 5. Java should be able to have an interpreter written for it (for better portability), and support parallelism and use dynamic typing.

    The Java platform refers to a group of software products from Sun Microsystems. The platform is used to develop and run Java programs. The platform includes the execution engine (called a Java Virtual Machine) that allows Java programs to do the same thing on different computer systems. This capability of being able to develop software on one platform and running it on other platforms is called "cross-platformcapability".

    There are many types of Java programs which run differently: 1. Java Applet- small program written in Java and that is downloaded from a website and executed within a web browser on a client computer. 2. Application- executes on a client computer. If online, it has to be downloaded before being run. 3. JAR file (Java archive) - used to package Java files together into a single file (almost exactly like a .zipfile). 4. Servlet - runs on a web serverand helps to generate web pages. 5. Swing application - used to build an application that has a GUI(windows, buttons, menus, etc.). 6. EJB- runs on a web server and is used to develop large, complex websites.

    Java is commonly used to teach students how to program as a first language, but is still also used by professionals. 1. Java requires that each variable be initialized. Some older languages such as C, allow variables to go uninitialized, which can cause random failures with mysterious bugs. 1. Java requires that each method declares a return type—the method should always return a value, except if its return type is void. This also prevents bugs. 1. Java comes with a large set of classes and methods, the Java APIthat can be used without having to develop as much code "from scratch". 1. Unlike C, Java primitive types, such as int, are always the same size in the number of bits which helps achieve cross-platform compatibility. 1. Java used to be thought of as being slower than C, but that's become less important in recent years because computers are faster. 1. Java has exception-handling that requires a programmer to handle error-conditions such as Input/Output errors. 1. Code compiled...

    Java has also been criticized. Some of the criticisms are: 1. Generics were added to Java in such a way so that existing code would still keep running. This was done using type erasure. This means that during compilation, the actual type of a generic argument is removed. This can lead to the Java interpreter to behave in unexpected ways at times. 1. Java has no unsigned integer types, which languages like C heavily use. This also means that it is impossible to directly exchange numeric data between C and Java programs. Cryptographyalso relies on such types to some extent; this makes it more difficult to write applications that use cryptography in Java. 1. The IEEE has defined a standard for floating-point arithmetic, IEE 754. Java only supports a part of the features of this standard.

    This article is or was the subject of a Wiki Education Foundation-supported course assignment. Further details are available on the course page. Student editor: Abharati. Peer reviewers: Abharati.

    This article has a section on 'editions'. But nothing on the differences between versions. Java 1.7 is in some ways quite a different languages from 1.0. Does anyone think there ought to be a 'Versions' section with brief notes on the main changes in each version? These could include links to information on the relevant topic elsewhere on WP.

    An editor has asked for a discussion to address the redirect Java. Please participate in the redirect discussion if you wish to do so. Steel1943 18:27, 11 November 2019

    There was a discussion for the deletion of the Java version history article here: Wikipedia:Articles for deletion/Java version history. I still don't see why the article was deleted as it was not a speedy deletion process and the result of the discussion was not delete. Furthermore, now: 1. there is hardly any history at all 2. there is still absolutely no explanation as what must be put in this kind of version history languages 3. 'all other major languages have the same articles with the same

    I propose to merge Java version history into Java #Versions. I see this as the natural follow up to Wikipedia:Articles for deletion/Java version history which was recently closed as keep. There is important information on Java version history, but the state of reliable sources about the subject remains unclear. Modernponderer helpfully linked to some sources at the deletion discussion, and I believe those sources are an excellent reason to include this information here, but I still don't see the

    Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 147.7 million people, Java is the world's most populous island, constituting approximately 55% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Much of the well-known part of Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and

    The origins of the name "Java" are not clear. One possibility is that the island was named after the jáwa-wut plant, which was said to be common in the island during the time, and that prior to Indianization the island had different names. There are other possible sources: the word jaú and its variations mean "beyond" or "distant". And, in Sanskrit yava means barley, a plant for which the island was famous. "Yavadvipa" is mentioned in India's earliest epic, the Ramayana. Sugriva, the ...

    Java lies between Sumatra to the west and Bali to the east. Borneo lies to the north, and Christmas Island is to the south. It is the world's 13th largest island. Java is surrounded by the Java Sea to the north, Sunda Strait to the west, the Indian Ocean to the south and Bali Strait and Madura Strait in the east. Java is almost entirely of volcanic origin; it contains thirty-eight mountains forming an east–west spine that have at one time or another been active volcanoes. The highest ...

    The natural environment of Java is tropical rainforest, with ecosystems ranging from coastal mangrove forest on the north coast, rocky coastal cliffs on the southern coast, and low-lying tropical forest to high altitude rainforest on the slopes of mountainous volcanic regions in the interior. The Javan environment and climate gradually alters from west to east; from wet and humid dense rainforest in western parts, to a dry savanna environment in the east, corresponding to the climate and rainfal

    Fossilised remains of Homo erectus, popularly known as the "Java Man", dating back 1.7 million years were found along the banks of the Bengawan Solo River. The island's exceptional fertility and rainfall allowed the development of wet-field rice cultivation, which required sophisticated levels of cooperation between villages. Out of these village alliances, small kingdoms developed. The chain of volcanic mountains and associated highlands running the length of Java kept its interior regions and

    Java is divided into four provinces and two special regions: 1. Banten, capital: Serang 2. West Java, capital: Bandung 3. Central Java, capital: Semarang 4. East Java, capital: Surabaya 5. Special Capital Region of Jakarta 6. Special Region of Yogyakarta, capital: Yogyakarta
